The Metro Green Line (formerly called the Central Corridor) is an 11-mile (18 km)[4][5] light rail line that connects the central business districts of Minneapolis and Saint Paul in Minnesota as well as the University of Minnesota. An extension is under construction that will extend the line to the southwest connecting St. Louis Park, Hopkins, Minnetonka and Eden Prairie. The line follows the path of former Metro Transit bus route 16 along University Avenue and Washington Avenue (which runs from downtown Minneapolis through the University of Minnesota main campus). It is the second light-rail line in the region, after the Blue Line, which opened in 2004 and connects Minneapolis with the southern suburb of Bloomington.
Construction on the Green Line began in late 2010.[6] It opened to the public on June 14, 2014.[7] The travel time between the downtown Minneapolis and downtown St. Paul stops is about 46 minutes.[5] The entire line originally operated 24 hours a day, seven days a week, but as of 2019 trains are replaced by buses from 2 am to 4 am on weekdays.[8] In 2018, the line carried a total of 13.8 million passengers.[2]
